Unlike passenger cars, trucks have developed much more slowly. Most of the models that you see on the roads today are not fundamentally different from those that came out 15-20 years ago. For example, most of the modern Kenworth models are very similar to the mid-1970s models, and although Tesla Semi wants to bring a more comfortable cab (not to mention new technologies), it is still firmly grounded in the beginning of XXI century.
On the other hand, this concept Audi HMV Concept represents a completely different story. This is what Optimum Prime should look like if it had some kind of imagination, or if the character was not based on the 1980s cartoon/toy line.
The Audi HMV was developed by designer Jeremy Dodd and has many elegant design elements that will usually go into the future. With towed trailing equipment there are a total of five lighting devices, three on the trailer and two on the tractor, the latter well integrated into the rear of the wheel arches.
If we had to guess, we would say that such a truck would be easily powered by electric motors and completely autonomous. We would not go so far as to say that he will finish the man behind the wheel, because then there will be no reason to build a real driver’s cab or tractor head, since the trailer will largely control itself.
